    Do these need a neutral or do they just switch line?

    Those usually need a neutral - I think you can get ones that only require a live supply only but they usually specify it and are quite ££££.

    • Terminate the cable into the NEMA socket observing the correct connections;
    “LI” = LIVE (Supply In)
    “LO” = Load (Supply Out)
    “N” = Neutral (The neutral to the load does not need to pass through the unit and can be taken directly)
    • Place the NEMA socket into the base holder with the arrow
    printed on the socket pointing towards North. If North is
    located behind the unit towards the mounting surface then
    the arrow should be aligned pointing in the direction of best

    Change of plan:laughing: The light will need to be switched by a PIR/photocell unit.

    Outside light.. to do the minimum amount of damage to decoration/avoid cable runs on the outside wall, i need to drill through the wall then with the minimum amount of pokey holes through the dot and dab, get up into the loft. I'm easily above the DB up there so will fit an switch, just for any maintainance - won't get used in normal use.
    I can't a cable get back down to the DB so is there any problem if i locate the lighting feed (or will it be a ring) and connect the new light feed to that via a wago box?

    the lights will all be on a radial so providing there looped at the lights there will be a permanent feed if its only one cable to the light that's switched only the feeds will only be at the switches

    The existing circuit loops round the switches rather than the light fittings otherwise i could have nicked a feed from the light in that room.
    I might just try and sneak a cable down to the light switch and get a feed from there.

    Are light circuits not on a ring?

    no just radial. you can take of the sockets but would have to fit a 13amp fused switch spur to drop down to 5 amp

    The production department wishes the planning department would stop changing their mind.

    So, switched by a photocell now.

    T&E out of the switch, run to photocell, then to the light. That will work, won't it?
